Abstract
Novel red organic electroluminescent (EL) dye, RED was developed for an application to the emission layer of EL device. Well known red material DCJTB was also used for comparison. Two kinds of devices were fablicated; one is ITO/ CuPc / TPD / 0.5% RED-1 in Alq3/ Alq3/ Li20/ Al and the other is ITO/ CuPc /TPD / 0.5% DCJTB in Alq3/Alq3/ Li20 / Al. External quantum efficiency of the EL device with RED was two times higher than that of the device with DCJTB. The maximum EL peak was detected at 635nm in the RED EL device.
